RESULTS OF TESTING OF SPRING RAPESEED HYBRIDS OF KWS COMPANY IN SOIL AND CLIMATIC CONDITIONS OF THE REPUBLIC OF TATARSTAN

Abstract

The research was carried out to study the productivity and adaptability of hybrids of spring rapeseed KWS Ethnos KL, Jazz KWS, Joshua KWS, Jungle KWS, KWS Jarus, Jerome on gray forest soils of the Republic of Tatarstan. Field experiments were carried out in 2021-2022 on the basis of Agrobiotechnopark LLC (Narmonka village, Laishevsky municipal District of the Republic of Tatarstan), laboratory analyses were carried out at the Agroecological Research Center of the Kazan State Agrarian University. According to the research results, it was found that according to the field germination of 6 compared variants of spring rapeseed, the hybrid Dnarus differed (field germination - 74%), this variant also had the highest seedling growth rate – 0.18 g/plant. In terms of resistance to pests and diseases, the hybrids Jarus and Jazz differed. Thus, according to these variants, the total number of affected plants from the total number of seedlings was minimal and amounted to 30.8 and 31.5%, respectively. On the same variants, there was maximum safety (38.4 and 36.5 pcs. m2) and plant height (128 and 119 cm). The formation of tall hybrids of Jarus and Jazz contributed to a decrease in the contamination of crops. In these variants, there was a minimum number of weeds – 7.6 and 7.9 pcs/m2, respectively. When analyzing the structure of the crop, the maximum indicators for all studied parameters were also in the hybrids Jarus and Jas, which ultimately contributed to the formation of maximum yields – 4.11 and 3.61 t/ha, respectively, for hybrids.
